Statistical Traffic Analysis Kit is a set of
command-line traffic analysis tools, designed to
help a network administrator to see what is
happening at a router at the moment. Unlike
tcpdump(1), the STAK utilities use statistical and
stream-oriented methods, and will never produce an
output stream at a speed beyond human perception.
The output is less accurate, however. STAK can
estimate overall traffic rates, determine which
nodes generate the most traffic, analyze traffic
between the LAN and particular external systems,
determine which connections generate the most
traffic, and extract strings from packets.
